Terminal, base station and communication method

Abstract

A terminal includes: a reception unit configured to receive from a base station: a block including a synchronization signal and a broadcast channel; a control channel carrying control information; and a shared channel carrying system information, based on the control information; and a control unit configured to perform an initial access to the base station, based on the system information. Information included in the broadcast channel includes at least one of information related to QCL (Quasi co-location), information related to LBT (Listen before talk), information related to DBTW (Discovery burst transmission window), and information indicating whether a band is a licensed band or an unlicensed band.

1 . A terminal comprising:
 a reception unit configured to receive from a base station: a block including a synchronization signal and a broadcast channel; a control channel carrying control information; and a shared channel carrying system information, based on the control information; and   a control unit configured to perform an initial access to the base station, based on the system information, wherein   information included in the broadcast channel includes at least one of information related to QCL (Quasi co-location), information related to LBT (Listen before talk), information related to DBTW (Discovery burst transmission window), and information indicating whether a band is a licensed band or an unlicensed band.   
     
     
         2 . The terminal as claimed in  claim 1 , wherein
 the information included in the broadcast channel is indicated by a bit value indicating a subcarrier offset from the block.   
     
     
         3 . The terminal as claimed in  claim 1 , wherein
 the reception unit receives information indicating an LBT type via a DCI (Downlink Control Information) field, and the control unit performs an LBT to which the LBT type is applied before starting transmission.   
     
     
         4 . The terminal as claimed in  claim 1 , wherein
 the reception unit receives information indicating an LBT type via a DCI field that is scrambled by RA-RNTI, MsgB-RNTI, or TC-RNTI, and the control unit performs an LBT to which the LBT type is applied before starting transmission.   
     
     
         5 . A base station comprising:
 a transmission unit configured to transmit to a terminal: a block including a synchronization signal and a broadcast channel; a control channel carrying control information; and a shared channel carrying system information, based on the control information; and   a control unit configured to perform an initial access to the terminal, based on the system information, wherein   information included in the broadcast channel includes at least one of information related to QCL (Quasi co-location), information related to LBT (Listen before talk), information related to DBTW (Discovery burst transmission window), and information indicating whether a band is a licensed band or an unlicensed band.   
     
     
         6 . A communication method performed by a terminal, the communication method comprising:
 receiving from a base station: a block including a synchronization signal and a broadcast channel; a control channel carrying control information; and a shared channel carrying system information, based on the control information; and   performing an initial access to the base station, based on the system information, wherein   information included in the broadcast channel includes at least one of information related to QCL (Quasi co-location), information related to LBT (Listen before talk), information related to DBTW (Discovery burst transmission window), and information indicating whether a band is a licensed band or an unlicensed band.
